do i need to adjust my 4 wheel linkage, after a 2 in lift.

I lifted my 01 xj 2 in, and lowered my trans with a skyjacker kit. I only used the blocks because the linkage still allowed by 4 part time and full time to engage. Now when I throw it in full time it seems to make more of a noise, and even a clunk when I romp on it in the snow/mud. the Part time works good, and the 4 lo ingages wierd now, it takes a minute to engage while moving forward then it kicks in. please let me know

If you dropped your tranny and x-case then yes you do.

Take the Drop down kit out, its not needed for the 2 in BB, but if you keep it in then you have to readjust the linkage for full engage
